Loom.

Application filed September 28, 1920. een no. 413,321,

To all whom it may concern:

- projecting arm k and an inwardly projectcitizen of the UnitedStates,residing at Paterson, in the county of Passaic and'State of NewJersey, have invented certain new and useful Improvements in Looms, ofwhich the following is a specification.

This invention relates to looms, and particularly to shuttle impellingmeans for looms of the class in which the shuttle-impellin'g or pickingmember is spring-pressedand is alternately cooked and released. The

invention consists in certain improvements in shuttle-impelling meanswhich have been already disclosed (but not claimediin an appli'cationfiled by one William S. Wells,

Serial No.343,599, and hereinafter set forth in the claims appended tothis specification. In the accompanying drawings, a

Figure 1 is a side elevation of a loom em-' clip on its'fulcrum m from aposition of contact with arm m to such a limit outbodying my invention;

Figure 2 is a section on line 2-2, F ignrel Figures 3 and 4 area sideelevation and a plan, on a larger scale, of certain parts appearing inFigures 1 and 2 Figures 5 and 6 are front and side elevations of thepicker stick mounting or car-- rier and Figures 7 and 8 are viewsillustrating the means for automatically cutting out thefixed, thepitman 7 connecting the: crankshaft with the lay or batten structure(c,*0Z,

e) and the hand wh'eel g forturning the crank shaft 6 manually are ormay be allthe same as in ordinary looms."

Themeans' now to be described, exceptas indicated, will be duplicated inthe' loom,

Y one at one side and the other at the other,

being adapted to: act in alternation, as will be understood','so as tothrow the shuttle back and forth.

A bracket generally designated by the 'character k and including asleeve is and a for- Ward upstanding arm 10 has its. sleeve fitted overand secured'to the"proj'ecting"end of the shaft 0 by screwsl-(Figure's 3and 4);

ing a rearwardly projectingweb 764' formed With an elongated upstandingoutwardly ing arm 76 On a' stud'k, projecting from arm 75 rearwardly ofthe same isfulcrumed a lever forming the carrier or mounting for 'the'picker" stick, the same being designated m in'Figures 1 and 3 and shownin' Figures 5 and6 as including a hub :mjournaled on stud is, adownwardly projecting arm m having a hardened plate m secured'theretoand projecting downwardly therefrom to" form ashoulder'm, an inwardlyprojecting arm wa and an upwardly projecting arm m; .a U-shaped clip mreceives between its branches the arm m and is pivoted therein on thestud m and above the clip there is suitably secured to arm m a loop mpreferably'of leather. The picker stick Wis embraced by the loop mloosely andis received and secured by a bolt 0 in and to the clip we,

so that the stick is freely movable with the 7 spring 1' which rests onthe web J0 and which, when the picking member m'is-swung to the positionshown in Figure 3, is adapted by the projecting plate m thereof tobe'de- 8 pressed and then catch and hold said memher in saidpositionQorcocked, the shoe having a hardened cocking shoulder s to.receive the contactof the shoulder m at that use; theupward movement ofshoe (1 may be limited by a set-screw Q. It will be understood" that'the"picker-stick n plays in 'a suitable slot-t "(Figure 1) in the batten eto the side of the loom, the springprojee.

ting forwardly :-'and having its end' arranged to pull downwardlyzonthe-arm m 'ofthe "picking 'memberthrough the medium ofa universal-jointconnection or :link 27 and. having means, as a set screw-28, foradjusting theipressure thereof. 7

- The cockingv and'tripping of the picking members is 1 accomplished bya 2 master ley'er v 29 for each picking member the same being fulcrumedon the frame side a and having its forward end projecting between theroller (on a stud 31 which projects from link 27) and the correspondingcocking shoe, there preferably being a set-screw 32 in said lever toimpinge against the shoe. hen the lever is oscillated it willalternately cook the corresponding picking memher, by impinging againstroller 30 as it rises, and trip it, by depressing the shoe 9 as itdescends, preferably through the medium of a device 41 to be described.3

A buffer 25' is provided to receive the downward impact of spring 25when lever 29 depresses the cocking shoe and so releases the pickingmember; otherwise such impact would be assumed by the cocking shoe.

' The movements of the two levers 29 of the two picking mechanisms (oneat each side of the loom) in proper time are effected from sprocketwheels 33, which have endless chains 34 extending around them andsprocket-wheels 35 on shaft 6, through pitmen 36 connecting eccentricpoints of sprocket-wheels 33 with the levers; only one of each of theparts 33 to 36 is shown.

I have illustrated means for preventing tripping of the picking membersand therefore cutting out their operation when the means for stoppingshaft Z2 and hence the loom is operated. Thus, 37 indicates a part ofthe means for stopping the loom (which means may be of any well knowntype) being here a lever at one side of the loom which, when thrown tothe dotted position in Figure 1, to stop the loom, depresses a rod 38which rocks a fork-lever 39- fulcrumed in the side frame, saidfork-lever in turn shifting a lever 40, fulcrumed on arm 7: from betweenthe lever 29 and the cocking shoe; lever 40 has a spring elevated button41 for transmitting the downward pressure of lever 29. to the cockingshoe, and

- member remains cocked. The two levers 40 (one at each side of theloom) may be con-' nected (Figure 7) so as both to be shifted and thuscut out both tripping members at the same time by the link 42. When theloom is turned over by hand there is a possi bility of the shuttleleaving the lay and missing the box, on account of the forward movementof the lay'being then too slow to keep the advancing lay against theshuttle f should it tend for any reason to veer forward in its flight,-and this creates an element of danger, especially since the shuttletravels at much greater velocity than in the ordinary case where it isimpelled'by tappet means. The advantage of cutti'ngout the action of thepicking means when the loom-stopping means is operated will there-' forebe apparent.

The invention is shown applied to a loom of the type in which thepicking member partakes of the back-and-forth or rocking motion of thebatten-including structure.

It considerably simplifies the mechanism and renders the same moresubstantial and durable and also accesslble and more easily adapted toan already existing loom to mount the principal actuators 25 and 29 onsaid train and hold the latter cocked when 35 moved in the otherdirection, and an actuating member movable in the supporting structurein one direction against said train to move the same to cooking positionand in the other direction against the cooking device to move the latterclear of said train.

It is also new to provide, in combination, with a supporting structureand the going driving member (as 7)) and stopping means (as 37) thereforof aloom, a cockable, spring-pressed picking member, a cooking shoe 9 orequivalent for said member, atrain of elements (as 34-, 33, 36, 29, 32and 40) actuated by the driving member and adapted to move the shoe orequivalent whereby to release the cooked picking memher, one element ofsaid train being withdrawable therefrom, and operative connecting means(as 40, 39 and .38)between said element and the stopping means, wherebyto control the release of the picking member. i

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is v I 1. In combination, a supportingstructure having a fixed portion and a batten-includ ing portion movableback and forth, a cockable picking member movable with and also back andforth in the movable portion of said structure, a plate-spring fixed inthe fixed portion of said structure and normally urging said member inthe direction for impelling the shuttle, a cooking device to hold saidmember cocked against the tension of said spring and movable to releasethe same, and means to move said member to cocking position and saiddevice to position to release said member in-alternation.

2. In combination, a supporting structure having a fixed portion and abatten-including portion movable back and forth, a cockable pickingmember movable with and also back and forth in the movable portion ofsaid structure, a platespring fixed in the fixed portion of saidstructure and normally *urging said member in the direction forimpelling the shuttle, a cocking device in the movable portion of saidstructure to hold said member cocked against the tension of said springand movable to release the same, and means to move said member tococking osition and said device to position to reease said member inalternation.

3. In combination, with a loom frame, a forward and back movablestructure arranged therein, a picking member movable with and also backand forth in the movable structure and having a laterally projectingarm, a spring member fixed in the frame and confined to move in anapproximately vertical plane and exerting pressure substantiallyvertically on said arm and thereby urging said member in the directionfor impelling the shuttle, and means to move said member in the contrarydirection preparatory to the impelling of the shuttle. v

4. In combination, with a supporting structure, cockable means includinga picking member movable back and forth in said structure and aspringnormally urging said means in the direction for impelling theshuttle, a cooking device movable in said structure and normallyheld inposition to engage said means and hold the latter cocked when moved inthe other direction, and an actuating member movable in said structureable back and forth in an upright plane and a spring normally urgingsaid means in the direction for impelling the shuttle, a cocking devicemovable insaid structure in an upright plane and normally held inposition to engage said means and hold the latter cocked when moved inthe other direction,

the first-named means to cocking position and the cocking device clearof said firstnamed means.

6. In combination, ,with a frame and, a

forward-and-back movable structure therein, a cockable means including apicklng member movable back and forth in said I 7 structure and a springsecuredto the frame and normally urging said memberin the direction forimpelling the shuttle, a cocking device movable in said structure andnormally held in position to engage said means and hold the lattercocked when said member is moved in the other direction, and

an actuating member movable in the frame,

in one direction against said means to move the same to cocking'positionand in the other direction against the cooking device to move the latterclear of said means.

7. In combination, with a supporting structure and the rotating drivingmember and stopping means therefor of a loom, a cockable spring-pressedpicking member movable in said structure, meansto hold said pickingmember in cocked position movable to release the same", a train ofelements actuated by the driving member and adapt- 'ed to move thesecond means whereby to release the cocked picking member, one ele mentof said train being withdrawable therefrom, and operative connectingmeans between said element and the stopping means.

In testimony whereof I afiix my signature.
